Noise Reduction With Insulation
In addition to slowing heat flow to keep a home comfortable, insulation provides a number of additional benefits. One of the most important is sound dampening, reducing outside or other interior noises. This can be especially useful in multifunctional homes, like those that serve as living and work spaces.
The type of attic insulation you choose will play a big role in how well it reduces unwanted noise. All insulating materials offer some sound-dampening properties, but some are more effective than others. Fiberglass, cellulose and spray foam insulation are some of the most popular choices for reducing sound in walls, floors, ceilings and attics. Each has its own strengths and considerations, but all are able to effectively block out unwanted sounds.
When determining how well an insulating material will reduce unwanted noise, density is the main factor to consider. The higher the density of an insulating material, the better it is at blocking out unwanted sound. Additionally, a material’s stiffness plays a role in its ability to control sound transmission as well.
Air-Sealing Foam Advantages: Improving Comfort and Efficiency
For example, fiberglass insulation manufactured into acoustic blankets, rolls, boards and duct liner is highly effective in reducing the transfer of airborne sound waves in residential, commercial and industrial buildings. This type of insulation is also commonly used in theaters, concert spaces and other public areas to increase speech intelligibility and provide a more pleasant environment for people to gather in. It’s also an ideal choice for reducing internal HVAC airborne noise in ducts and pipe insulation systems.
